I used to shoot wood but they break too easy and the amount of work you have to put into a set wasn't worth it too me.  Carbons are tough and in the long run are way cheaper (cost) than woods.  Unless you loose one or just plain shoot them into a brick wall, a carbon arrow will last indefinitely and shoot way better than anything else.  Oh well...to each his own.

Beaver, I have to concur with Steertalker.  Carbons are initially expensive but I have some Carbon Express 250's that are so old I can't remember how many times I've refletched them.  As well as being super tough they are also resistant to moisture.  Now if you shoot wood because well,it's wood....that's cool.  I like the thought of shooting wood for all of the noramal tradional reasons but I don't think saving money is one of them.
